Abstract
The adaptive threshold circuit (FIG. 1) senses the amplitude of a digital signal relative to a threshold and generates a corresponding output signal therefrom. Feedback circuitry generates a correction signal which drives the threshold toward a predetermined level in the signal-eye pattern. This predetermined level passes only through the region of intersymbol interferene in the signal-eye pattern.
